Former Celtics star Paul Pierce learned the hard way not to bet against the Knicks after his bold Game 2 prediction backfired spectacularly – resulting in an unforgettable 20.2-mile robe-clad commute through LA.

"If the Celtics lose Game 2 at home, I promise you, I am walking here tomorrow," Pierce had declared on FS1. "I guarantee this one. Put the house on this game." Spoiler: The Celtics choked another 20-point lead, losing 91-90.

True to his word, Pierce hit the streets at 5 a.m. Pacific time Thursday, documenting his journey via Instagram Live. "All right, time for me to get to steppin’," he said, calling himself a "man of my word." Though he wisely opted for sneakers over bare feet, his plush bathrobe became an instant sidewalk spectacle.

"I can't believe the Celtics got me out here like this, dog," Pierce laughed in a later update. "I’m really walking out here like this." Along the way, he entertained hecklers ("You lost that bet, huh?") and clocked his progress – finally arriving at work around 1 p.m., proving even NBA legends pay their debts (in sleepwear).

Never bet against New York – unless you're ready to become LA's most stylish pedestrian.

Possible Preaching Angles:

1) Integrity means keeping your word—even when it costs you (even if it’s embarrassing). 2) Don’t count on what you believe the future holds - only God knows the future.
